https://github.com/thundernest/import-export-tools-ng/blob/v14.0.0/xpi/beta/import-export-tools-ng-14.0.0-b6-tb.xpi This works.

no it's not supported by ver 115.0.1??? i also don't know what i'm supposed to do with it?? download it?? how do i attach it to thunderbird?? i don't design these programs i just use them & complain about them, thanks for working with me

Thunderbird does not design it either. These addons are created by people in their own time and they are responsible for any development. The authors rely on those who are regular users to donate to maintaining the addon.

david pointed you to a beta version which you could try.

re: i also don't know what i'm supposed to do with it?? download it?? how do i attach it to thunderbird??

You download and install the xpi file. At the link which david gave you - see earlier comment. You will notice an icon on the right and if you hover over it it says 'download raw file' - click on it. The 'import-export-tools-ng-14.0.0-b6-tb.xpi' file will get downloaded to computer Downloads file or where you have set up to receive downloaded files.

Then you need to get it imported into Thunderbird. Nothing has changed since the dawn of time on importing addon .xpi files. So I would expect you may already know the following process.

• In Addons & Themes
• Select ' Extensions'
• Click on the 'cog wheel iocn and select 'Install addon from file'
• locate the .xpi file you downloaded and select it.
• clickon Open
• Follow instructions and it gets installed into Thunderbird.

This mentions feedback on the current testing of the beta version.

i've donated to Thunderbird every year since i first downloaded it in 2016 but don't know if any of those donations get to developers for add ons?? i always willingly donate to free software apps & products that i don't pay for but can't live without so please let me know if there is another way to donate to developers of addons

Thanks for asking. Yes, developers often go with no thanks or donations, as they are not part of the Thunderbird organization. I suggest you click tools>addons and then click an addon and then click the homepage for the addon. That is generally where an ability to donate will appear. You will definitely put a smile on someone. :)

i don't see the homepage available on this addon???

It's there, but there is no donation option. Some authors do this just out of personal enjoyment. If you click the Reviews in lower right of that screen, you can leave him a comment. Thanks for your interest.

re :i've donated to Thunderbird every year since i first downloaded it in 2016 but don't know if any of those donations get to developers for add ons??

All Thunderbird donations go to developing Thunderbird, add functions, help fix security bugs and maintain this website etc.

All addons are totally independent of Thunderbird. They are created by people like you and me, users of Thunderbird. Authors of addons do it for various reasons, but maintaining them to keep up with versions of Thunderbird is time consuming.

Where to find donate/contribute links. At this link there is a 'Contribute' icon: https://addons.thunderbird.net/en-us/thunderbird/addon/importexporttools-ng/

In Thunderbird 'Addons & Themes' select 'Extensions' Where you see the ImportExportTools NG addon - look on the right and you will see a 3 dot icon - click on it and select 'Manage' Under 'Details' - scroll down and you find a 'Contribute' button - click on it and it will open in your browser.
